Bio Midterm Review Quiz - Unit 1

Johnny is training for a 10K race and wants to make sure he wears the most effective pair of shoes. He normally wears Nike shoes, but he wants to compare them to other brands of shoes: Hoka, Saucony, Brooks, and Adidas. For the next month, he will test out each brand of shoes. On Week 1, he will wear Hoka brand shoes for his daily run (always the same route, distance, and time of day). At the end of the week, he will count and record the number of blisters on his feet and compare that to the number of blisters he has when wearing his usual Nike shoes. He will repeat this process for Week 2 (Saucony), Week 3 (Brooks), and Week 4 (Adidas).

What is the INDEPENDENT variable?

• Number of blisters

• Total distance of runs for the week

• Brand of shoes

• Number of weeks
